SE42.01 Ocean basins and continental margins: Mid-ocean ridge processes and structure of the oceanic lithosphere

Event Information

This session will welcome talks and posters presenting the results of recent cruises and of modeling work on all aspects of mid-ocean ridge dynamics: the physical and chemical aspects of mantle melting, melt extraction, melt transport and the mode of emplacement and crystallization of magmatic rocks at fast and slow spreading ridges; ridge tectonics and the mechanisms of unroofing of lower crustal and mantle-derived rocks at mid-ocean ridges; hydrothermal processes, the characteristics of crustal aquifers, the heat and chemical budget of crust-seawater interactions at the ridge axis and in ridge flanks environment, as well as the biochemical processes associated with the development of life within the crust and deep biosphere, at hydrothermal vent sites, and analogous systems conjectured to exist elsewhere in the solar system.
